Geometry
Droste
The picture inside itself, spiralling inward without end.
Controls
- ratio
- How much smaller each turn is than the last. This is what decides how fast the picture disappears into itself
- turns
- How many turns the spiral makes while the picture shrinks by that ratio. At zero it is not a spiral but nested rings
- centre x
- A number from 0 to 1, 0.5 by default.
- centre y
- A number from 0 to 1, 0.5 by default.
- zoom
- How close the picture is taken in the widest turn. Above one only its middle falls into the funnel
- rotate
- Turns the finished picture, the way you would turn a print in your hands. The spiral shape itself is unchanged
